ROTARY CUTTING; TOOL.

Application led January 2, 1923. Serial Io. 010,402.

To all whom it may concern.'

Be it known that I, HARRY Burssnn, a Russian citizen, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and use-ful Improvement in Rotary Cutting Tools, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part, of this specification.

ily invention relates to a rotary cutting tool shown in the accompanying drawings and more particularly described in the following specification and claims.

The object of my invention is to provide a rotary cutting tool constructed of high speed steel having cutting facesat right angles to each other whereby it is especially adapted for key cutting machines--the construction being such that two right angle surfaces may be` cut at one or the same operation.

A further object of the invention is to provide a device adapted to co-ordinate with other like devices and to be assembled upon a mandrel or other rotary machine element for use as a cutting tool.

vIVith the foregoing and other objects in view which will appear as the description proceeds the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter de- 35 scribed and claimed, it being understood that changes may be made in the'precise embodiment of the invention herein disclosed with-v out departing from the spirit of the same.

In the dra-wings accompanying this speci- 4o lication:

Figure 1' is a sideelevation of the tool showin an annular projecting rim having a plura ity of cutting teeth.

Figure 2 is an edge view of the tool havingrtwo cutting rims spaced apart.

igure 3 is a central cross-sectional view through the device showing two projecting annular cutting iian es.

Figure 4 is a mo ification of the device 5o showing two annular cutting tools, arranged in abutting relation upon a mandrel, or other` rotatable element,-shown in dotted lines.

Figure 5 is a fragmentary cross-sectional view of one of the elements, shown in the M .preceding ligure.

Figure 6 isa fragmentary cross-sectional view of a modification showing the tool provided with cutting rims of .relatively different widths spaced apart, the recess between the cutting rims being angular instead of arc-shaped in crosssection as shown in the preceding views.

Figure 7 is a fragmentary' perspective view showing the cutting surface provided on the edge and also the side of the tool.

Referring now to the letters of reference placed upon the drawings A denotes a rotary cutting tool provided with a bore B to receive a mandrel C,which may be provided with a key D,-as indicated in dotted lines in Figure 4,-extending into a slot projecting from the bore, whereby the tool may be rigidly secured to the mandrel.

E, E, are annular flanges projectin laterally from the web F of the tool. G, are rims spaced apart provided with cutting teeth H on the rims G, G, and the annular flanges E, E.

The tool may be provided with one or a plurality of cutting rims G if desired and when more than one rim is employed it may be spaced apart b either an arc-shaped groove I or an angu ar groove J as shown in Figure 6. When constructed as shown in the latter figure the tool may be used for 'cutting grooves corresponding in depth to tha: ofthe projecting rims of the cutting too In Figure 4 I have indicated a modiiication in which two rotary cutting tools are assembled in contiguous relation upon a mandrel. It will also be obvious that any desired number of these tools may be arranged upon a shaft in adjacent or spacedrelation to each other as may be required.

It will now be seen that the tool ma be employed to cut two right-angle sur aces at the same operation or one or more grooves in the face, and annular grooves on the side of the element being operated on. 100

Having thus described my invention what I claim is:

1. A rotary disc cutting tool of the class described comprising a cut-tiner rim and an annular projecting cutting liange with a central bore whereoy .it is adapted for longitudinal adjustment uon spindle, and means for securing sai rotary disc cutting tool to the spindle.

2. A rotary cutting wel of the class de- 110 v scribed com rising cutting rims spaced from, a right and left right-angle cut may be made each other m combination with an annular at one and the same operation.
